Question

question 10 (1 point) saved listen which of the following would be the least soluble in water? a) ch3ch2ch2ch2nh2 b) ch3ch2nh2 c) ch3ch2ch2ch2ch2ch2nh2 d) ch3nh2 e) ch3ch2ch2nh2

Explanation:

Solubility in water for amines depends on the balance between the polar amino group (\(-NH_2\)) which can form hydrogen bonds with water (favorable for solubility) and the non - polar hydrocarbon chain (unfavorable for solubility). As the length of the hydrocarbon chain increases, the non - polar effect becomes more dominant. Among the given options, \(CH_3CH_2CH_2CH_2CH_2CH_2NH_2\) has the longest hydrocarbon chain.

Answer:

C. \(CH_3CH_2CH_2CH_2CH_2CH_2NH_2\)
